Ugh! That looks like a cooked video card.
I am no longer a tech so I am out of the loop, but I have seen my share, and had some of my own go, and they look like that(the website graphics)
I am going to guess that this is new behaviour, I would wonder if you are doing ANY overclocking? Either system, vid card, or both?
(Before I go further I just have to say that would be a BIOS setting and if you don't have experience with that stuff, then I wouldn't fool around with it)disclaimer just in case;)
If so, try default settings and see what that does.
I would also wonder if you recently changed drivers.
If so, and this happens across the board i.e. Windows programs, internet browser, games, I would rollback the driver.
For kicks you could try to reinstall DirectX.
That's about all i can think of ATM.
small edit
when I saw the post title I thought of a joke post, like:
Oh yes that is just the Viewer Scramble/Jam Transmission artifact. The AI pirates sometimes employ this so you can't see your starmap. It passes after five minutes, and they may use it again as soon as ten minutes.
But seeing your pics, I figured that wouldn't be very funny.
